balance and should be able to satisfy a wide range of students and practitioners. It is organized well with suitable illustrative problems and with ample problems for solution at the end of each chapter. The part of the book titled "Basic Mathematical Concepts" provides an excellent introduction to vectors, matrix operations, and convex sets. The concepts are treated with sufficient depth to provide a good introduction to those with a limited background. The second part of the book starts out with models and applications. The author provides the standard problems of product-mix, blending,and planning. The use of diagrams in model formulation are helpful and again the problems at the end of the chapter are abundant although not very challenging. The more mathematically inclined may get impatient with the lengthy discussion in the chapter titled "Geometric and Economic Interpretation". However in a textbook directed to a diverse group this is not out of place and should give students a good 'feel' for linear programming. The next chapter,which treats the simplex method as a computational procedure, is compact and presents the basic algebraic approach of transformations. This chapter may come as a rude shock to the reader who may have
